Trace View and Trace Navigator are two new features from Sentry, designed to help developers quickly identify the root cause of performance issues in their applications. These features provide a more conversational approach to monitoring, allowing users to drill down into specific transactions and errors to gain a deeper understanding of their application's performance. With Trace View, users can connect slow-loading dots across multiple projects and see how code progresses from initial calls to final queries. Trace Navigator provides a minimap view that allows users to navigate related errors and children transactions, while also showing metadata such as device, OS, and browser information. By using these features, developers can quickly identify and solve performance issues, reducing the time spent on debugging and improving overall application reliability.
